I used to run the Runecast service account with readonly privileges. It has been sufficient up to version 2.7.x. Even the hardware compatibility check (beta) did work with readonly privileges. After upgrading my appliance to version 3.0.0 (GA), I found a notification. Missing privileges..

Runecast 2.7.0 with ESXi Upgrade Simulator

New publications in IT-Administrator Magazine

Optimization, troubleshooting and monitoring of virtual infrastructures is like a scientific subject in itself and one of my IT-passions. Together with my buddy Dr. Jens Söldner I have published two articles in german IT-Administrator magazine (German Language), which cover the subjects above.

First article covers strategies for vSphere troubleshooting, best practises and useful tools like VeeamOne, RVTools, vRealize Log Insight or Runecast-Analyzer.

Second article covers vSphere management, administration, automatization and deployment.

Enable SSH cluster-wide with PowerCLI

This article shows how to quickly enable SSH service on one, more or all hosts in a cluster.

Start service

Login to vCenter.

Connect-VIServer <myVC>

The command below will activate SSH on all hosts registered in in your vCenter.

Get-VMHost | Get-VMHostService | Where Key -EQ "TSM-SSH" | Start-VMHostService

TSM means “Technical Support Mode”

Stop SSH service

To stop SSH service on all hosts, use the command below.

Get-VMHost | Get-VMHostService | Where Key -EQ "TSM-SSH" |  Stop-VMHostService -Confirm:$False

Selective activation

It’s possible to limit the scope of the command to one host. Just add the FQDN after Get-Host.

Get-VMHost myESX.myDomain.local | Get-VMHostService | Where Key -EQ "TSM-SSH" | Start-VMHostService
